The Evoulution 100 is an awesome engine! I overpowered my Twist 40 with it and it screams with
a 14x6 which I will tach and send results. I am a 2 stroke fanatic and love the simplicity of this
engine, ck out the low speed idle adjustment, it doesn't get any easier. I know my plane is smaller
than yours but the 100 should still be more than adequate for Funtana 90
